Step-by-step explanation:

Answer 2

Answer:

$\mathbb\purple{SOLUTION}$

$= \frac{1}{2} + \frac{2}{5} + \frac{1}{7}$

LCM of 2 , 5 and 7 is 70

$= \frac{1}{2} \times \frac{35}{35} = \frac{35}{70}$

$= \frac{2}{5} \times \frac{14}{14} = \frac{28}{70}$

$= \frac{1}{7} \times \frac{10}{10} = \frac{10}{70}$

Now add all numbers together.

$= \frac{35}{70} + \frac{28}{70} + \frac{10}{70}$

$= \frac{35 + 28 + 10}{70}$

$= \frac{73}{70}$
